-9.8 m/s because she is basically falling and -9.8 is gravity
Answer:
a) 35 sequndos b) M1 = 600m M2 = 875m
Explanation:
a)
Antes de que el otro móvil comience a moverse, el primer móvil ha viajado 5 segundos a una velocidad de 15 m / s.
5 segundos x 15 m / s = 75 metros.
Podemos establecer una ecuación con la información que conocemos. Juntos, en total, los dos recorren 1475 metros.
Voy a representar el tiempo como t. Un móvil ya ha recorrido 75 metros y hará otros 15 t. El otro aún no se ha movido y viajará 25t. Esos tres números se sumarán a 1475.
75 + 15t + 25t = 1475.
Resta 75 de ambos lados y suma términos similares de t: 40t = 1400
t = 35 segundos.
b)
Ahora tome la distancia recorrida por cada vehículo por separado y conecte 35 segundos para t.
Primer móvil: 75 + 15t = 75 + 15 (35) = 600m
Segundo móvil: 25t = 25 (35) = 875m

Answer:
0.44m/s
Explanation:
drift velocity=I/nAq
diameter 12 gauge
wire=0.081inches=0.081*2.5=0.2025cm radius=0.10125cm area=pi*R^2 =20/8.5*10^22*3.14*0.10125^2*10^-4*1.6*10^-19*
V = 0.44m/s
The andromeda galaxy is approaching our galaxy with a radial velocity of 120 km/s. given the galaxies present separation of 800 kpc, and neglecting both the transverse component of the velocity and the effect of gravity in accelerating the motion, estimate when the two galaxies will collide.
The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy that is 2.5 million light-years away from Earth and the closest big galaxy to the Milky Way. It has a diameter of roughly 46.56 kiloparsecs.
The Milky Way, which houses the Solar System and Earth, and the Andromeda Galaxy are anticipated to collide in roughly 4.5 billion years. This galactic collision will take place between the two largest galaxies in the Local Group. The Andromeda galaxy is the brightest galaxy outside of our solar system. It is the furthest object that the majority of us humans can see with our unaided eyes at a distance of 2.5 million light-years.
